220-1201 Practice Test 35 — 15 Questions

Question 1

A technician is troubleshooting a display that shows a 'ghost' image of a previous screen that fades slowly. The monitor is a 4-year-old IPS panel. What is the most likely cause?

Accepted Answer

The LCD panel has image retention or burn-in.. Ghosting or image retention on an IPS panel is often due to burn-in or temporary image persistence. This occurs when static images are displayed for long periods, causing the liquid crystals to not fully relax. It is a hardware defect that may be irreversible.

Answer

The monitor's response time setting is too low.

Answer

The video cable is causing signal interference.

Answer

The monitor's refresh rate is set incorrectly.

Question 2

During a deployment, you install a new graphics card into a desktop PC. After powering on, the system boots but the display is blank. The monitor is known to work, and the card's fans spin. What should you check next?

Accepted Answer

Check that the monitor cable is connected to the graphics card, not the motherboard. Fans spinning indicates the card is receiving power, but a blank display often means the monitor is not receiving a signal. The most common oversight is connecting the display cable to the motherboard's video port instead of the new graphics card's ports.

Answer

Replace the graphics card

Answer

Update the BIOS

Answer

Reseat the RAM

Question 3

A technician is deploying several Android tablets for use as point-of-sale (POS) terminals. The tablets must run a custom POS app in kiosk mode, preventing users from accessing other apps or settings. Which configuration method should the technician use?

Accepted Answer

Use a Mobile Device Management (MDM) solution to configure kiosk mode.. This question tests knowledge of mobile device management (MDM) and kiosk mode deployment. The correct approach is to use an MDM solution to lock the device into a single-app kiosk mode, which is a standard enterprise feature for dedicated devices.

Answer

Enable Developer Options and set the app as the default launcher.

Answer

Install a third-party launcher and hide all other apps.

Answer

Root the tablets and modify the system partition to block other apps.

Question 4

A small business uses an MFP that also functions as a network scanner. Users can scan to a shared folder on a Windows PC, but some users get an 'Access Denied' error when scanning. Other users can scan successfully. What is the most likely cause?

Accepted Answer

The MFP's scan-to-folder credentials do not have write permissions to the shared folder.. Scan to folder requires the MFP to have write permissions to the shared folder. If the MFP uses a generic service account, that account must have appropriate NTFS and share permissions. The issue is likely permission-related for the MFP's credentials.

Answer

The network switch port is faulty.

Answer

The MFP's firmware is outdated.

Answer

The Windows firewall is blocking the MFP.

Question 5

A customer reports that their new desktop PC runs for exactly 30 minutes and then shuts down. After the shutdown, the system won't power back on for several minutes. What is the most likely BIOS/UEFI-related cause of this behavior?

Accepted Answer

The BIOS thermal protection feature is triggering due to CPU overheating.. This scenario describes thermal shutdown protection. The BIOS/UEFI monitors CPU temperature via sensors and will shut down the system to prevent damage if temperatures exceed safe thresholds. The delay before restarting allows the CPU to cool down.

Answer

The BIOS has a power-on password enabled.

Answer

The BIOS is set to the wrong CPU multiplier.

Answer

The UEFI boot order is set to network boot first.

Question 6

A user reports that their PC emits a continuous series of short beeps and will not display anything on the screen. The system was working fine after a recent RAM upgrade. What is the most likely cause of this issue?

Accepted Answer

The new RAM is incompatible or faulty. Continuous short beeps typically indicate a power supply failure or a motherboard power issue. However, given the recent RAM upgrade, it is more likely that the new RAM is incompatible or not seated correctly. The technician should first reseat the RAM and try the original modules to isolate the problem.

Answer

The CPU is overheating

Answer

The graphics card is not seated properly

Answer

The motherboard is shorting against the case

Question 7

A user complains that their PC is running slowly and the fan is constantly running at high speed. Task Manager shows the CPU is consistently at 100% usage even when idle. Which of the following is the most likely cause?

Accepted Answer

A background process is consuming CPU cycles, such as a mining script or system update. High CPU usage at idle is often due to background processes, such as malware or a runaway application. The constant high fan speed indicates the CPU is generating excess heat from this activity.

Answer

The CPU is overheating due to dried thermal paste

Answer

The power supply is failing and cannot provide enough power

Answer

The CPU has been overclocked beyond its limits

Question 8

A customer complains that their Wi-Fi signal is weak in a specific conference room. You need to measure the signal strength and identify potential interference sources. Which tool is best suited for this task?

Accepted Answer

Wi-Fi analyzer. A Wi-Fi analyzer (Option B) is specifically designed to measure wireless signal strength (RSSI) and identify interference sources such as overlapping channels, co-channel interference, or non-Wi-Fi devices (e.g., Bluetooth, microwave ovens) by displaying real-time spectrum usage and channel utilization. This tool provides the granularity needed to diagnose weak signal in a specific area, unlike generic tools that lack wireless analysis capabilities.

Answer

Spectrum analyzer

Answer

Cable tester

Answer

Multimeter

Question 9

A technician is troubleshooting a VoIP phone that intermittently drops calls. The phone uses SIP (Session Initiation Protocol) for signaling and RTP (Real-time Transport Protocol) for audio. Which ports are typically used by these protocols?

Accepted Answer

SIP: 5060, RTP: 16384-32767. SIP typically uses port 5060 (UDP or TCP) for signaling, and RTP uses a range of UDP ports (often 16384-32767) for audio streams. Port 80 is HTTP, port 443 is HTTPS, and port 1720 is H.323 (another VoIP protocol).

Answer

SIP: 80, RTP: 443

Answer

SIP: 1720, RTP: 5060

Answer

SIP: 443, RTP: 80

Question 10

A company's web server is accessible from the internet, but users report that the website loads slowly. The server's public IP is 203.0.113.10, and the internal IP is 192.168.1.10. The network administrator notices that the router's port forwarding rule is set to forward port 80 to 192.168.1.10:8080. What is the likely cause of the slow performance?

Accepted Answer

The port forwarding rule uses the wrong internal port. Port forwarding should map external port 80 to the server's internal port 80, not 8080 unless the server listens on 8080. If the server listens on port 80, the mismatch causes connection delays or errors as the router forwards to a closed port. Correcting the internal port resolves the issue.

Answer

The DNS server is misconfigured

Answer

The NAT table is full

Answer

The DHCP scope is exhausted

Question 11

A company is migrating its fleet of 100 desktops from Windows 10 to Windows 11. The IT department needs to enable TPM 2.0 and Secure Boot on each system via the UEFI. Some older systems have TPM disabled by default. Which UEFI setting must be changed to enable TPM?

Accepted Answer

Enable TPM in the UEFI security settings and set the boot mode to UEFI.. TPM (Trusted Platform Module) is often disabled by default in the UEFI firmware. It must be enabled in the security settings of the UEFI. Additionally, the system must be set to UEFI mode (not Legacy) with Secure Boot enabled for Windows 11 compatibility.

Answer

Update the UEFI firmware to the latest version from the manufacturer.

Answer

Disable the integrated graphics to free up resources for TPM.

Answer

Set the SATA controller to RAID mode.

Question 12

A user reports that their virtual machine is running very slowly. The host system has 16 GB of RAM, and the VM is configured with 8 GB. The host is running a Type 2 hypervisor on Windows 10. The technician checks Task Manager and sees that the host is using 14 GB of RAM. What is the most likely cause of the VM's poor performance?

Accepted Answer

The host does not have enough free RAM to support the VM's needs. The host is running low on available RAM because the VM's allocated memory is not being released efficiently, or other host processes are consuming memory. In a Type 2 hypervisor, the host OS manages memory, and if it is oversubscribed, the VM will experience swapping and slowdowns.

Answer

The VM's virtual CPU is overclocked

Answer

The hypervisor is not compatible with Windows 10

Answer

The VM's network adapter is set to NAT instead of bridged

Question 13

A technician is tasked with building a high-performance workstation for a data scientist who uses large datasets. The workstation has a motherboard that supports quad-channel memory. The technician has four 16 GB DDR4-3200 modules. Which configuration will yield the best memory performance?

Accepted Answer

Install one module in each of the four channels (e.g., slots 1, 3, 5, 7) to enable quad-channel mode.. Quad-channel memory architecture requires that all four memory channels be populated with identical modules to achieve maximum bandwidth. Installing one module per channel (e.g., in slots 1, 3, 5, 7 or the designated quad-channel slots) allows the memory controller to access all four channels simultaneously, quadrupling the data transfer rate compared to single-channel. Using fewer modules or mismatched sizes would reduce the channel count or cause the system to run in a lower-channel mode.

Answer

Install all four modules in the same channel (e.g., slots 1, 2, 3, 4) to maximize density.

Answer

Install two modules in one channel and two in another, leaving the other two channels empty.

Answer

Install all four modules in the same slot using a special adapter.

Question 14

A user complains that their computer boots slowly and shows a 'Press F1 to continue' message every time. The firmware settings appear to have lost their configuration. What is the most likely cause?

Accepted Answer

The CMOS battery is failing. A failing or depleted CMOS battery cannot retain BIOS settings, causing defaults to load and often requiring user intervention at boot. This is a common issue that leads to the 'Press F1' prompt. The question tests understanding of CMOS battery function in maintaining firmware settings.

Answer

The boot order is incorrect

Answer

The hard drive is failing

Answer

The BIOS version is outdated

Question 15

A technician is configuring a new workstation for video editing. The user needs fast read/write speeds for large project files. Which storage technology should be selected for the primary drive?

Accepted Answer
